5 Abstract of thesis presented to the Senate of Universiti Putra Malaysia in fulfillment of the requirement for the degree of Doctor of Philosophy DIVERSITY, ECOLOGY, AND DISTRIBUTION OF NON-INDIGENOUS FRESHWATER FISH IN MALAYSIA By KHAIRUL ADHA BIN A.RAHIM January 2012 Chairman: Associate Professor Siti Khalijah Daud, PhD Faculty: Faculty of Science Introduction of non-indigenous species have resulted in major global change, harming indigenous species and communities throughout the world and also have caused enormous economic damage. Thus, the main objectives of this study were to examine the composition, ecology, and distribution of non-indigenous fish species in natural water bodies and also evaluate the role and contribution of non-indigenous fish species through aquaculture or stock enhancement in socio-economic development in Malaysia. The studies were carried out at five locations in Peninsular Malaysia and six locations in Sabah and Sarawak. The habitats surveyed in Malaysia include rivers and streams in highland and lowland areas, floodplain and large river system, rice fields, irrigation canal, ex-mining lakes, national park, and estuaries. A total of 4055 individual fish representing 150 species belonging to 38 families were captured. This included 67 species and 24 families from Peninsular Malaysia, and 113 species from 30 families of indigenous fish as well as non-indigenous from Sabah and Sarawak. Out of 150 fish species, 17 species from eight families were identified as non-indigenous. The family iii

6 Cichlidae represented the highest species collection (5 species) followed by Cyprinidae (4 species), two species from families of Clariidae and Pangasiidae, and one species from families of Charachidae, Helostomatidae, Belontiidae and Loricariidae respectively. The present study has shown that non-indigenous fish occurred and inhabited diverse habitats including highland and isolated streams, rivers, rice fields, swamps, drainage, dam and reservoirs, ex-mining lakes and estuaries in Malaysia. The intentional and unintentional introduction of non-indigenous fish species for various purposes, such as aquaculture development, aquarium fish industry, recreational fishing activities, natural disasters, biological control, and continuous released by Buddhist followers as part of their religious activities have caused a widespread distribution and establishment of nonindigenous species in local ecosystems. In addition, the occurrence of non-indigenous species, not only changed the structure of indigenous ichthyofauna group but also caused ecological and economical damages to local fishermen. The present finding provided evidence that there are no restrictions or limitation of spreading of non-indigenous fish in natural habitats of Malaysia. In the present study, a total of 42 non-indigenous species were recorded. Based on the records and field surveys, the number of introduced fish species was increased almost double than the previous records. Most of the species introduced mainly for aquaculture development and only a few introduced fish species for recreational fisheries, biological control and aquarium fish industries. The aquaculture industry has also encouraged iv

7 introduction of aquaculture species and has become the major reason for introducing non-indigenous fish species into Malaysia. The non-indigenous fishes that have been introduced for food fisheries and aquaculture development include Chinese carps (Hypophthalmichthys nobilis, Cirrhina molitorella, Ctenopharyngodon idella, Cyprinus carpio, Hypophthalmichthys molitrix,); Indian carps (Catla catla, Cirrhina mrigala, Labeo rohita); Javanese carp (Barbonymus gonionotus); African catfish (Clarias gariepinus) and broadhead catfish (Clarias macrocephalus); snakeskin gouramy (Trichogaster pectoralis) and red promfet (Colossoma sp). The tilapias (Oreochromis spp.) together with their hybrids such as Mozambique tilapia (Oreochromis mossambicus), Nile tilapia (O.niloticus, O. urolepis hornorum), hybrid tilapia (O. hornorum and O. mossambicus, red tilapia hybrid) and redbelly tilapia (Tilapia zillii) are also the important species in aquaculture development in Malaysia. This study has recorded a potential new species, Scortum barcoo, for aquaculture development in Malaysia. It showed that the rate and number of non-indigenous fishes introduced in local habitat has greatly increased since the early twentieth century. v

8 Abstrak tesis yang dikemukakan kepada Senat Universiti Putra Malaysia sebagai memenuhi keperluan untuk ijazah Doktor Faslafah EKOLOGI, KEPELBAGAIAN, DAN TABURAN SPESIS IKAN ASING AIRTAWAR DI MALAYSIA Oleh KHAIRUL ADHA BIN A.RAHIM Januari 2012 Pengerusi: Profesor Madya Siti Khalijah Daud, PhD Fakulti: Fakulti Sains Pengenalan spesies asing bukan sahaja telah menyebabkan kesan perubahan secara global seperti ancaman kepada spesies tempatan dan komuniti, tetapi juga telah menyebabkan kesan negatif kepada ekonomi. Oleh itu, tujuan utama kajian ini adalah untuk mengenalpasti komposisi spesies, ekologi dan taburan spesies ikan asing di habitat semula jadi, dan menilai peranan dan sumbangan spesies ikan asing dalam pembangunan sosio-ekonomi di Malaysia melalui pembangunan akuakultur. Kajian ini telah dijalankan di lima lokasi di Semenanjung Malaysia dan enam lokasi di Sabah dan Sarawak. Habitat yang telah dikaji termasuklah sungai dan anak sungai di kawasan tanah tinggi dan rendah, dataran banjir dan sistem sungai yang besar, sawah padi, tali air, tasik bekas lombong, taman negara dan juga di kawasan muara. Sebanyak 4055 individu ikan daripada 150 spesies yang mewakili 38 famili telah ditangkap. Ini termasuklah 67 spesies daripada 24 famili di Semenanjung Malaysia dan 113 spesies daripada 30 famili ikan tempatan dan juga ikan asing di Sabah dan Sarawak. Daripada 150 spesies ikan vi

9 tersebut, 17 spesies daripada lapan famili merupakan spesies ikan asing. Sebanyak 5 spesies ikan asing dari famili Cichlidae, diikuti oleh Cyprinidae (4 spesies), dua spesies daripada keluarga Clariidae, dan Pangasiidae dan satu spesis dari keluarga Charachidae, Helostomatidae, Belontiidae dan Loricariidae telah dikenalpasti. Kajian ini menunjukkan bahawa spesies ikan asing telah hadir dan mendiami pelbagai habitat dari kawasan tanah tinggi dan terpencil, sungai, sawah padi, paya, saliran, empangan dan takungan, tasik bekas lombong dan kawasan muara sungai di Malaysia. Kemasukan spesies ikan asing secara sengaja dan tidak disengajakan adalah disebabkan pelbagai tujuan seperti pembangunan akuakultur, industri, ikan akuarium, aktiviti perikanan rekreasi, bencana alam, kawalan biologi dan perlepasan ikan berterusan dari pengikut Buddha dalam kepercayaan agama mereka. Kegiataan ini telah menyebabkan taburan dan penyebaran spesies ikan asing menjadi lebih meluas di ekosistem tempatan. Selain itu, kehadiran spesies ikan asing di dalam ekosistem tempatan bukan sahaja telah merubah struktur komposisi semulajadi spesies ikan tempatan, tetapi juga telah memberi kesan buruk kepada persekitaran dan ekonomi nelayan tempatan. Penyelidikan ini telah mendapati bahawa tidak ada sebarang sekatan atau halangan kepada penyebaran ikan asing dalam habitat semulajadi Malaysia. Sebanyak 42 spesies ikan asing telah direkodkan dalam kajian ini. Berdasarkan rekod dan hasil dari kajian lapangan, kadar kemasukan spesies ikan asing di negara ini telah meningkat sebanyak dua kali ganda daripada yang telah dicatatkan sebelumnya. Kebanyakan spesies ikan asing yang dibawa masuk ke Malaysia adalah untuk tujuan pembangunan akuakultur, perikanan rekreasi, kawalan biologi dan juga untuk industri vii

10 ikan akuarium. Industri akuakultur telah juga menggalakkan lagi pengenalan ' spesies ikan akuakultur ' yang juga menjadi penyebab utama pengenalan spesies ikan asing ke Malaysia. Spesies ikan asing yang telah dibawa masuk untuk perikanan makanan dan pembangunan akuakultur termasuklah ikan kap Cina (Hypophthalmichthys nobilis, Cirrhina molitorella, Ctenopharyngodon idella, Cyprinus carpio, Hypophthalmichthys molitrix,); Kap India (Catla catla, Cirrhina mrigala, Labeo rohita); lampam jawa (Barbonymus gonionotus), ikan keli Afrika (Clarias gariepinus) dan ikan keli bunga (Clarias macrocephalus), ikan sepat (Trichogaster pectoralis) dan bawal merah (Colossoma sp). Spesies ikan Tilapia seperti Oreochromis mossambicus, O.niloticus, O. urolepis hornorum, bersama dengan spesies tilapia hibrid (O. hornorum dan O.mossambicus, juga merupakan spesies penting dalam pembangunan akuakultur di Malaysia. Kajian ini telah mencatatkan satu species berpotensi baru, Scortum barcoo untuk pembangunan akuakultur di Malaysia. Ia menunjukkan bahawa kadar dan spesies bilangan ikan asing yang diperkenalkan di dalam habitat tempatan telah menunjukkan peningkatan sejak awal abad ke-20. viii
